Allure (2018)

Plagued by the abuse of her past and the turmoil of failed intimate encounters, Laura struggles to find a lover and a sense of normalcy. Her beacon of hope comes in sixteen year-old Eva, a talented pianist disillusioned by the life her mother imposes upon her. An unlikely relationship is formed between the two and Eva becomes an obsession to Laura. In light of Eva's unhappiness, Laura convinces her to runaway to her house and they soon find themselves caught within an intense entanglement. Manipulation, denial and codependency fuel what ultimately becomes a fractured dynamic that can only sustain itself for so long.
